This manuscript describes a FACS-based protocol for isolation of papillary and reticular fibroblasts from human skin. It circumvents in vitro culture which was inevitable with the commonly used isolation protocol via explant cultures. The emanating fibroblast subsets are functionally distinct and display differential gene expression and localization within the dermis.

FAQs
Mechanical and enzymatic dissociation provide complementary ways to release cells from prepared skin tissue. Mechanical handling separates tissue physically, while enzymatic treatment helps dissociate the tissue into individual cells or smaller cellular groups. Selecting and controlling these steps affects whether researchers obtain viable populations suitable for culture or downstream analysis.
Careful dissection concentrates the sample on the skin region relevant to the experiment, while removing unwanted structures reduces material that could interfere with cell recovery or interpretation. These preparation steps help researchers obtain a more appropriate starting sample before dissociation, improving the likelihood that the resulting cells represent the intended skin population.
Viability and identity depend on handling the sample carefully throughout dissection, dissociation, separation, and culture. Excessive disruption may reduce the number of living cells, whereas inadequate separation can leave mixed or poorly defined populations. Maintaining controlled culture conditions after isolation supports continued study of cells while preserving their usefulness for biological analysis.
These populations represent different cellular components of skin and can support different experimental questions. Keratinocytes, fibroblasts, and immune cells may be isolated as separate or mixed populations, depending on the study design. Identifying which population was recovered is important when interpreting results involving barrier function, tissue regeneration, infection, wound healing, or disease.
A typical workflow begins with obtaining and dissecting the skin sample, followed by removal of unwanted structures. The prepared tissue then undergoes mechanical or enzymatic dissociation to release cells. Researchers may subsequently separate relevant populations and place them under controlled culture conditions for primary culture, engineered tissue models, or downstream analysis.
Isolated cells are useful when experiments require defined cellular populations, primary cultures, or controlled examination of cell behavior. This format can support studies of wound healing, aging, infection, skin disease, and regeneration. It also enables researchers to use selected skin cells in engineered tissue models or therapeutic development rather than examining only the original tissue sample.
The process can provide viable skin cell populations for studying cellular responses, tissue formation, and disease-related changes under controlled conditions. Depending on the recovered population, researchers can investigate barrier function, regeneration, infection, aging, or wound healing. The resulting cells may also contribute to engineered tissue models and evaluations relevant to therapeutic development.
